DEVICE FOR INFLATING CUSHIONS FOR INVALIDS BEDS, CHAIRS, OR THE LIKE.

Specification of Letters Patent.

Application filed August 26, 1913. Serial No. 786,804.

To all whom it may concern Be it known that I, OATHARINA ANDRE- snN,born GLAUSEN, subject of the German Emperor, residing at Busehau, nearSchleswig, Germany, have invented certain new and useful Improvements inDevices for Inflating Cushions for Invalids Beds, Chairs, or the like,of which the following is a specification, reference being had thereinto the accompanying drawing.

The drawing shows an example of object of my invention.

Figure 1 shows vertical section through cushion, Fig. 2 vertical sectionthrough bail, and Fig. 3 horizontal section through both valves and thebail with cheeks.

On the air cushion a is placed the mouthpiece with the two checks 0 andd and the iii-suction valve 6 with the fastening nut f. In the twocheeks c and d there are for each bail g and 72, two perforations and 0,so that these bails, according as they are to be used or not, can bepulled out farther or shoved in deeper; Figs. 1 and 2 show these bailspulled out, while in the same figures the bails are shown shoved in indotted lines. Through the upper check 0 there passes the opening 5,which is closed by the valve 70. Between the two checks 0 and (Z is thebellows Z. For pulling the two cheeks together there is applied thespring we in the interior of the bellows. If the air cush ion is to beinflated, the two bails g and h are pulled out, the lid f of the Valve 6is loosened and then the two checks 9 and h are pressed together (seeFig. 2) thereby the two cheeks move apart, the bellows stretches andthrough the valve 0 the hollow space re sulting becomes filled with air.I-Iereupon the two bails are released and the spring at pulls the twocheeks together, whereby the air escapes through the valve is into theair cushion. This 0 eration is repeated until the cushion is su cientlyfilled with air and then the lid f is turned fast. Then the two bailsare pushed back again. If it is desired to remove the air from thecushion, the outlet valve at a suitable point is unscrewed.

IIaving now described my invention and the manner of using it, what Iclaim and desire to secure is 1. In a device for inflating air cushions,the combination of a mouth piece two cheeks connected at one side tosaid mouthpiece and having sockets thereon, bails at each side of saidmouthpiece and extending into said sockets, and longitudinally movabletherein and a flexible wall between said cheeks operated by said bails.

2. In a device for inflating air cushions, the combination of amouthpiece having an inlet valve, two cheeks connected at one side tosaid mouthpiece and having sockets therein, bails at each side of saidmouthpiece and extending into said socket and longitudinally movablethereinbellows in said cheeks operated by said bails and a spring insaid bellows to normally hold said bellows in a closed position.

I11 an air cushion inflating device the combination of a mouthpiece, avalve therein, bails supported by said mouthpiece and longitudinallyadjustable therein, a bellows connected with said mouthpiece and holdnormally closed by a spring and valves adapted to admit air into saidbellows when the bails are compressed and to admit the air from saidbellows into the cushions when the bails are released.

4. In an air cushion inflating device, the combination of a bellows,bails thereon adapted to be longitudinally adjusted, and operating whenopen to expand said bellows, and a spring in said bellows operating toclose the latter and to open said bails and valves whereby air isadmitted into said bellowsjand forced into said cushion as specified.

In testimony whereof I aflix my signature in the presence of twowitnesses.
